Flowers of Evil, Volume 2 (Flowers of Evil #2)
Shuzo Oshimi

Contrary to Takao's predictions, the girl he was falling for, Nanako Saeki, responds by eventually accepting the bibliophile for who he is. Or at least, who she thinks he is. In the second volume of Flowers of Evil, Takao's lies have given him new life with his now new girlfriend Nanako. And as he becomes closer to Nanako, his relationship with Sawa only deepens as the "contract" they share weighs heavily on the teen.
